I'm very serious about installing a 144" kit to my 08 nytro rtx. I ride trail and off trail. Probably 60% aggresive trail and 40% off trail. I have been looking at the cobra and ripsaw. I'm al ittle worried about hyfax wear on trail but can deal with a little extra wear as long as its not extreme. Whats everybodies experience on these tracks or others. Was wondering if the new ripsaw lit 1.75 x 146 can be addapted to work. Any thoughts would be appreciated. Any recomendations on no slip drivers for this application.
 
I normally don't particularly like the ripsaw tracks, but the 1.75 ripsaw looks a lot better to me than the shorter lugged versions. The 1.75x146 could definitely be used and it would probably be very nice. You would, however, have to change your drivers to 2.86 pitch. You can order it ALL from tracksusa.com. The only thing you really need to be concerned about is that with the 146" track, the back wheels need to be situated a whole inch further back than with a 144". If you're doing the conversion, then be sure that what you do will give you enough space.

The other option I would suggest is the Arctic cat 144x1.25 track part number 1602-191, which is a 1.25x144 PREDATOR track. Camoplast used to sell it direct with the part number 9873 (if I recall correctly), and it will perform very well both on and off trail.

The other options are less than stellar. Ripsaw is very delicate, and the lugs on cobra (and other 144" crossover tracks) are very thin. The only other 144" track that gives me the impression of being fairly durable is the freeride, only problem is that its only 14" wide. It will work though.
 
Forgot one thing... 8 tooth 2.86 pitch is equivalent to 9 tooth 2.52 pitch in terms of diameter -- means the same gearing is good. A 9 tooth 2.52 might be a good idea -- it would lower the gearing by a little over 10% to help spin that track and it would help pick up for the extra track length, HOWEVER, be sure to measure everything to make sure that it will give you enough clearance to fit the track... you will DEFINITELY need to remove the front heat exchanger protectors, but even then, I can't say for certain that it will fit.
 
I just did the math on it and a 9 tooth 2.86 should fit with the 1.75" track. The radius on the 9 tooth is 1/2" greater than the 8 tooth, the 1.75" track is 1/2" greater than the 1.25, so it requires an extra 1" of clearance. Removal of the tunnel protectors will provide that extra inch, but not more than that. It should be measured though, just to make sure.
 
I went with the 1.75" camoplast backcountry track. I havent' used it yet, but I think it is going to be the ticket. I'd say I do 40/60 trail/off trail. The lugs on this track seem pretty durable to me.
 
We have good results with the Camo Backcountry 144 but they are not designed to run on trail. If you want to try it as a crossover track you must run scratchers and hyperfax (high melting point). Both are available from Tom Hartman.

Im running the backcountry track om my RTX, great track for offtrail riding and not the best on the trail.
The luggs are a little to soft imo.
I have absolutely no issues with slider wear.
I put on 1300 miles last season, riding everything from powder to icy conditions, and the sliders stay on for this season too. Measured my sliders last week an they were 16mm at the thinnest point. (Wear limit is 10,5mm)
If i were to buy a new track today it would be the Intense 1,75".
